NHC monitoring two systems

NEW ORLEANS -

The disturbance the Gulf Coast region has been monitoring in the Caribbean for the past few days hasn't shown any signs of strengthening after it passed over the Yucatan Peninsula, but that could change as the storm enters the Gulf of Mexico Friday.

Regardless, the system is struggling to get organized and it's approaching less than favorable conditions for that to happen.

The system has a 50 percent chance of tropical cyclone development, the National Hurricane Center said Friday morning.

Satellite images indicate that the area of low pressure, labeled Invest 92L, has moved offshore of the Yucatan Peninsula and over the southwestern Gulf of Mexico.

Although the shower and thunderstorm activity is currently disorganized, the NHC said environmental conditions could become more favorable for development if the low moves toward the west or west-northwest over the next couple of days.

If the system takes a more northward track, it would move into a less conducive environment for further development.

An Air Force reconnaissance aircraft was initially scheduled to fly into the disturbance, but that mission was scrapped.

Tropical Storm Erin weakened to a tropical depression in the eastern Atlantic and poses no threat to land.
